The electric fluoropolymer-lined ball valve is a widely used device in industrial control. Driven by an electric motor, it automatically controls flow in pipelines. The valve mainly consists of a valve body, ball, transmission device, actuator, and fluoropolymer lining. The fluoropolymer lining has excellent oxidation, corrosion, and high-temperature resistance, providing excellent protection against various corrosive media.
Electric fluoropolymer-lined ball valves are widely used in chemical, petroleum, power, metallurgical, and pharmaceutical industries, and are particularly suitable for pipeline systems containing corrosive media. This valve features high automation, simple structure, and good sealing performance, ensuring the stability and safety of the pipeline system.
Electric fluoropolymer-lined ball valves also feature easy operation, long service life, and low maintenance costs. Operation is simple, requiring only following the instruction manual and minimal manual intervention. The valve's relatively long lifespan meets the long-term needs of industrial production.
The electric fluoropolymer-lined ball valve is a control device capable of stably and automatically controlling flow in pipeline systems containing corrosive media, and has broad application prospects.

Fluorine-Lined Electric Ball Valve Structural Features
- Fluoropolymer Lining: The valve body cavity and ball are lined with 2.5–3 mm thick F46 or F4 fluoroplastic, resistant to acids, alkalis, and highly corrosive media.
- Sealing Structure: Employs a soft-seal valve seat for excellent sealing performance. The valve core is an "O"-shaped ball for reliable shut-off.
- Actuator: The electric actuator features a built-in servo system, supporting 4-20mA signals and 220VAC/380V power supply control, eliminating the need for a separate servo amplifier.
Fluorine-Lined Electric Ball Valve Advantages
Strong corrosion resistance
Fluoroplastic linings can withstand strong acids (such as sulfuric acid and hydrofluoric acid), strong alkalis (such as sodium hydroxide), organic solvents (such as dichloromethane), and oxidizing media (such as chlorine) of any concentration, and have a wide applicable temperature range (-50℃ to 180℃).
Compared to stainless steel valves, fluoroplastic-lined valves are resistant to highly corrosive media such as hydrofluoric acid and concentrated nitric acid, and are 30% cheaper.
Excellent sealing performance
The combination of a soft-seal valve seat and a fluoropolymer-lined spherical surface achieves zero leakage, making it suitable for conveying high-purity media.
The actuator has a built-in position sensor that provides real-time feedback on valve status and supports remote monitoring.
Flexible and convenient operation
Electric drive enables remote or automated control over a distance of up to 1000 meters. No air source is required, making it suitable for scenarios without compressed air.
It switches quickly, requiring only a 90° rotation to open and close, with low flow resistance and strong flow capacity.
Reliable and durable structure
The valve body is precision cast using investment casting, resulting in high strength and a smooth appearance; the lining is free of pinholes (leakage detection voltage ≥15kV), ensuring a long service life.
Equipped with overload protection, manual emergency function, and automatic reset clutch, ensuring safe valve reset in the event of power failure.
